Navisa,
The ZoneInfiltration:FlowCoefficent model is described in the
ASHRAE handbook of fundamentals (Chapter 27 in the 2005 edition). The flow
Coefficient is a property of the building determined using a blower door test and
can also be derived from a leakage area. The other coefficients are tabulated
in the ASHRAE chapter for various building heights, foundations, etc.
Hope that helps,
Neal Kruis

Subject: [EnergyPlus_Support] Zone Infiltration-Flow coefficient model
While using this model to simulate
infiltration, how do we arrive upon the flow coefficients to be entered? How do
we combine all surfaces i.e doors, windows, external walls, roof for these
coefficient values?
Thanks,
Navisa Jain
